My invention aims to provide certain improvements in j ournal boxes for railway cars to permit a reduction in cost of manufacture.

j The accompanying. drawings illustrate an embodiment of the invention. 7 I i q 'Fig. 1 is a half plan and half horizontal section of the cellar of a journal box;

Fig. 2 is a vertical longitudinal section of 3 the same;

Fig. 3 is a transverse vertical section of the same on the line 33 of Fig.1;

of Fig. 1, showing only the upper part. Figs. 5 and 6 are similar views of a modifled detail. I Referring to the embodiment of the invention illustrated, the showing isdirected to,

the cellar only of the box. The cellar is made in twosegments welded together. One segment is made of cast steel or similar metal and forms the top 1 with projecting portions 2 which constitute an arch bar seat with lateral flanges '3 openings 4; this segment including also downward flanges 5 which constitute inside stop pieceswithvertical grooves6 in their outer faces. V

' The lower segment is stamped out of sheet 0 metal and constitutes the bottom 7 and sides 8 of the cellar. The sidesare bent in to form 9 which register and look into the grooves 6 in the inside stoppieces, and which are in line also with the bolt openings 4 inthe flanges of the top segment.

The top 1 is flanges 10 (Fig. 4;) wh ch come down'to the upper edges of the sides 8 of the lower segment and are weldedthereto,

In'the alternative constructions shown in Figs. 5 and 6, the flange 1 0 of the upper segment is grooved so as to bring the edges down 'on both sides of the lower segment 8. In

Fig. 6, in addition,,.there is a raised rib 12 along the center of the'groove in the edge of r the flange 10; which rib concentrates the area Fig. 4 is a similar section on the line4t I facilitates through which the current passes and thus weld. j with great particularity of detail certain embodiments of my lnvention, yet it isn otto be understood the invention is restricted to therefrom that the particular embodiments described.

pieces; and a sheet metal lower segment hav- 1ng grooves at the sides registering with said stop pieces and in line with said bolt openings', the cast upper segment having flanges on its lower face abutting against the edges of the sheet metal lower segment and having flanges beyond said stop pieces projecting down on the outside of the lower segment,

said segments being welded together along the abutting edges of the flanges and the I lower segment. 7 V

In witness whereof, I have hereunto signed myn'ame. l r j THOMAS E. MURRAY, Jn.
